If the shape is 2-dimensional, then it is called a polygon. A polygon of 5 sides is a PENTAGON.
A WRIGGLE.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
The equation for the perimeter of a shape depends on the shape itself. For a rectangle, the perimeter can be calculated using the formula: P = 2(l + w), where l is the length and w is the width. For a circle, the perimeter is called the circumference and can be found using the formula: C = 2πr, where r is the radius. For other shapes, such as triangles or irregular polygons, the perimeter is found by adding the lengths of all the sides.
4 - w = 7 subtract 4 from each side 4 - 4 - W = 7 - 4 - W = 3 divide both sides by - 1 ( remember, the implied coefficient of w is - 1 ) (- 1/- 1)w = 3/- 1 w = - 3 =======check in original equation 4 - (- 3) = 7 4 + 3 = 7 7 = 7 ========checks
A shape w/ 11 sides is called a hendecagon.
If the shape is 2-dimensional, then it is called a polygon. A polygon of 5 sides is a PENTAGON.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
for a 4 sided shape... w+w+L+L=perimeter perimeter is the outside of a shape. add all of the sides to get the perimeter.
w/2 - 18 = - 7 Add 18 to both sides of the equation w/2 = - 7 + 18 w/2 = 11 Multiply both sides by 2 w = 11 x 2 w = 22
A WRIGGLE.
The lengths of the sides of a shape with more than 3 sides does not provide enough information to determine its area.

L + W = P/2 = 18. In ratio of 7:2 sides are 7/9 x 18 and 2/9 x 18 ie 14 and 4
the outside edge of a shape e.g if it was a square the formula would be P=(L)x(W)x2 or in simpler terms add up all the sides of the shape
